Luceri等人之其他實例顯示對置通道、衛生墊襯一面一 個。此種配置之缺點是衛生棉易上曲或下凹地彎曲,性能 較無法預測。 相同之啃試,Richards於1977年11月22日所申請之USP 4,059,114揭示一種具有網狀凸紋之吸收墊。此種配置之 衛生棉頂面中亦具凸紋,且視上述流體操作特性而定。而 < 且,衛生棉頂浮凸之通道致使其易於向上漥曲结構下彎曲 ,並非較佳向上漥曲结構。Romans-Hess等人於19δ7年4 月7日申請之USP 4,655,759.中亦發現類之唯試*其揭 示一種具有與縱向側緣相鄰之浮凸通道之衛生棉*其使側 / - 面染色減至最少,消除洩露,並使衛生棉側邊於使用時保 持向上褶曲。 技藝界中於衛生棉之頂面中提供縱向減弱線之其他嗜試 包括Glassman於1967年9月所申請之USP 3,343,543 ;
